Atmosphere Settings

The atmosphere settings holds settings that controls the atmosphere

Property	Function
Render Resolution	The resolution of the internal render textures used for atmosphere rendering. Lower values like 128 or 256 are fine and more performant since the atmosphere color changes gradually, increase only if needed. This is a static and performance sensitive parameter.
Sun Disc Size	The apparent size of the sun disc.
Sun Bloom	The intensity of the sun's corona.
Planet Scale	The radius of the planet in kilometers. This affects the horizon line. This value is relative to 6371000 meters, which is the average radius of Earth.
Atmosphere Scale	The thickness of the atmosphere in kilometers. This affects the height of the atmosphere from the horizon line. This value is relative to 100000 meters, which is a reasonable scale for atmosphere thickness.
Mie Scattering	The mie scattering coefficient. This controls the size and intensity of the mist around the sun.
Density	The density of the atmosphere. This controls the overall intensity of the atmospheric scattering.
Exposure	The exposure of the atmosphere. This controls the overall brightness of the atmosphere.
Enable Celestials	Enables rendering of the moon and stars. This is a static and performance sensitive parameter.
Night Sky Color	The color of the sky at night. This color comes to play when the sun is below the horizon.
Ground Color	The color of the ground.
Air Density	Rayleigh atmospheric scattering coefficients for air molecules. This is responsible for the blue color of the sky and the reddening of the sun near the horizon. You can tweak these values to achieve different atmospheric colors or to simulate other planets' atmospheres.
Ozone	Absorption coefficients for ozone. This removes specific colors from the light beam. Mostly affects the color of the sky near the horizon, especially during sunrise/sunset. You can tweak them to achieve different atmospheric colors or to simulate other planets' atmospheres.
